TEMP HI: High alarm status for temperature measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
TEMP LO: Low alarm status for temperature measurement.
0 = (Default) Last measurement was equal to or above threshold setting.
1 = Last measurement was below threshold setting.
